the Total surface area increases and the chemical composition remains the same .
Pyroclastic describes a rock formation mostly consisting of rock fragments from volcanoes or crushed during an eruption.
Cinder Cones are composed of rock fragments and the eruption of cinders. The rock fragments pile up around a single crater forming a Cinder Cone.
Basalts
The fan-shaped pile of broken rock fragments at the base of a steep bedrock slope or cliff is known as a talus slope or talus cone. This debris results from the weathering and erosion of the bedrock above, where gravity causes the rock fragments to accumulate at the base of the slope.
Crushed stones are typically referred to as crushed stone or crushed rock. These crushed fragments are commonly used in construction and landscaping for a variety of purposes such as making concrete, paving driveways, and drainage applications.

Rockfall.
The movement of rock fragments is called erosion.
Rockfall.
This may be known as a scree slope or a talus pile. Talus and scree are normally used interchangeably, however scree normally refers to material of gravel size or smaller and talus to larger debris.
Rock fragments are called sediments and by a process called lithification they turn into sedimentary rocks. Lithification is made up by compaction and cementation which is by pressure and a natural glue that is formed from groundwater the sediments stick together and then harden into rock.
